Design and Construction Highlights

The starter features a sealed, high‑density iron housing that protects internal components from moisture, dust, and vibration. Inside, the motor employs a precision‑ground armature coil wrapped with high‑quality enamel insulation to withstand repeated electrical surges. The integrated ball bearing assembly ensures smooth rotation and reduces wear, extending service life even under heavy cranking loads.

Vehicle Compatibility

This starter is engineered for a broad spectrum of models, including but not limited to:

• Fiat Doblo (various body styles)
• Fiat Punto (2‑door and 4‑door variants)
• Fiat Strada Pick‑Up
• Lancia Delta, Ypsilon, and other compact cars
• Alfa Romeo models sharing the same engine architecture

Engine codes such as 1845 (1.8 L) or 2.0 kW variants are fully supported, ensuring a perfect fit for both petrol and diesel engines within this family.

Installation Procedure

1. Disconnect the battery: Remove the negative terminal to prevent accidental short circuits.
2. Remove the old starter: Unbolt the mounting flange and detach the electrical connections. Keep track of the wiring harness orientation.
3. Position the new starter: Align the mounting flange with the engine block, ensuring that the gear teeth mesh correctly with the flywheel or flexplate.
4. Tighten bolts: Secure the starter using the supplied torque specifications (typically 25 Nm).
5. Reconnect wiring: Attach the high‑current connector and the low‑voltage control wire, respecting polarity.
6. Reattach battery: Reconnect the negative terminal first, then the positive.
7. Test start: Activate the ignition to verify smooth cranking and proper operation.

Maintenance Tips

• Inspect the starter housing for cracks or corrosion every 20,000 km.
• Check the electrical connections for tightness; loosened terminals can cause high resistance and overheating.
• Replace the starter if you notice excessive noise, sluggish cranking, or a failure to start after repeated attempts.
